Those disks are all, so far as I can tell, original-condition floppy disk images. For example the accessories disk is still packed.

If there's an FTP site I should upload all that stuff to, please let me know.

Getting away from STOS for a second, I have all the discovery pack disks imaged, and I have the third (but not first) manual scanned as well as the STOS one. I also have a full set of manual scans for Prospero C including, box included, but no disk images I'm afraid. Prospero C was given away on an ST review coverdisk, though - issue 17. I have that issue scanned, but don't have the following several for the tutorial series.

I've contributed some ST-related book scans to http://dev-docs.atariforge.org/ and some magazine scans to http://www.atarimania.com/list-atari-magazines.html a while back - these STOS and Prospero C manual scans a new and I might have a few more scans hanging around that I haven't uploaded anywhere yet - I'll do some checking. I *think* I have five new issues of Atari ST User, 3 issues of ST Review and a couple of ST Actions, but probably no new ST-related books/manuals outside the STOS and Prospero ones. I do have a copy of Illustrating Basic by Alcock scanned, though, and a second-edition "Dabhand Guide" C book with sections about the Atari ST and Amiga.

In case all that scanning etc isn't crazy enough, I've been trying to figure out all the STOS 1.xx official version numbers and find/reconstruct disk images. There's a fair bit of guesswork involved so I'd appreciate any corrections. Obviously Mandarin encouraged people to apply updates to their original disks, the packed accessories disk was inconvenient etc - updates didn't update everything, but the STOSV204, STOSV205 and STOSV206 updates were fairly thorough. It's e.g. more than possible that the two different 1.03 compiler disk variants really result from people applying the STOS 2.6 update to the STOS 2.5 variant, then also replacing the unwanted STOSV205 update program.

Anyway, here we go...

Main STOS package...

- 1.01 to 1.03 - these were all STOS 2.3. There were no functional changes to the language disk in these versions - CONFIG.BAS changes between 1.01 and 1.02, but the ASC listing is unchanged. The 1.01 versions was possibly still in a pre-release BAS file format. On the accessories disk, STOSCOPY.ACB gets a change between 1.02 and 1.03. The games disk had some changes between 1.01 and 1.02 - BULLET level 4 was dropped, a level each from ORBIT and ZOLTAR were modified, and there was a bugfix to BULLET.BAS. I've only been able to get the French 1.01 (TOSEC) but the 1.02 and 1.03 UK versions are available to download. The only changes between UK/French releases seem to be one byte in the EDITOR.ENV on the language disk and perhaps the DESKTOP.INF on the accessories disk (the French TOSEC accessories disk is unpacked, and didn't preserve that).

- As far as I can tell, 1.04, 1.05 and 1.06 didn't exist as actual releases. They probably refer to three updaters - the STOSV204 update from STOS Compiler and compatibility updates for TOS 1.4 and TOS 1.6. STOSV204 reduces the float precision for speed, giving STOS 2.4. The two TOS compatibility updates both apply to STOS 2.3 and STOS 2.4 (and to the compiler disk) and give compatible versions of STOS 2.3/STOS 2.4. That is, you can have TOS 1.4 or TOS 1.6 compatible versions that identify as STOS 2.3 or as STOS 2.4 - you can have the STOS 2.3 big slow floats yet still have compatibility up to TOS 1.6 if (for some bizarre reason) you really want. Three version numbers seem to count for five variants.

- 1.07 was STOS 2.5 - the "proper" TOS 1.6 update, also I believe sold as an updated package. This forces the floating point update and some other changes in addition to being TOS 1.6 compatible. The accessories disk packing is changed. The games disk is version 1.04, but identical otherwise to version 1.03. There's a fair amount of guessing here - I don't have a non-updated 1.07 set of disks. Reconstruction is based partly on various run-only shareware games, partly on the fact that the ST User release seems to be 1.07 with an update applied, and partly on comparison with what the STOSV205.BAS update (from compiler 1.03/2.5) produces.

- 1.08 was STOS 2.6 - the TOS 1.62 update. The games disk is version 1.07, still referring to STOS 2.5, and has a ZOLTAR.BAS bugfix. There are three updates that all produce the same thing from older language disks - the TOS 1.62 update often distributed with the Fun School 2 update, the STOSV206.BAS from a compiler disk, and the UPL.PRG from STOS 3D.

Compiler versions...

- 1.01 was the initial release with the STOS 2.4 updater.- 1.02 is one of my most tenuous guesses. It seems to be the compiler version I had all those years ago, but my original disks got lost before I could image ST disks on a PC. From surviving files from one DOS-formatted STOS working disk it was still STOS 2.4, not TOS 1.4 compatible, and had a modified BASIC204.LIB (the interpreter update was unchanged). Presumably a library bugfix release. 1.02 also seems to have been shortly after the Maestro release, where 1.01 was shortly before, so the tweak to STOSRAM.ACB in 1.03 (increasing the default ramdisk size to allow for the Maestro compiler extension) was probably first included in 1.02.- The TOS 1.4 and TOS 1.6 compatibility updates can both be applied to version 1.01 and 1.02 Compiler disks, which remain the "same" version, just compatible with the extra TOS versions.- 1.03 comes in two flavors - one includes a STOS 2.5 update, one includes a STOS 2.6 update. The compiler itself updates to suit for each, so there's a 1.03 for STOS 2.5 and a 1.03 for STOS 2.6. The STOSV205.BAS and STOSV206.BAS updates are a single file each, without a folder of files to copy as with STOSV204.BAS for 1.01 and 1.02.- STOS 3D includes updates for the language disk and compiler disk. The language disk update just ensures it's at 2.6. The compiler disk produces compiler version 2.7, with no 1.0x version number AFAICT.

- ST Format release was a cut-down STOS 2.6/1.08- Discovery pack was a slightly different cut-down STOS 2.6/1.08- ST User release seems to have been a complete STOS 2.5/1.07 with the STOS 2.6 update applied, and with a 1.03/2.6 compiler. Effectively STOS 1.08/2.6, but with some remnants (and some extra files such as the TOME21 interpreter extension).

Maestro versions...

- 1.01 - the version most people have including me.- 1.02 - this is speculation, based on finding a distinct variant of the compiler extension that isn't provided by the 1.01 disks and doesn't seem to be produced by any update AFAICT, though I haven't done much checking yet. With so little to go on there's no way I can attempt to reconstruct this.

STOS 3D versions...

- 1.01 - as far as I can tell, this is the only version sold as a box, but...- 1.11 - this version seems to have been available as packed (complete) disk contents from shareware libraries about three months after the original release, which seems pretty odd.

I think I've found all the official updates. The Page 6 Magazine ST library had a different-floppy-disk-change-message STOSV204.BAS and the TOS 1.6 and TOS 1.62 updates. The STOSV204.BAS included with the TOS 1.6 update is corrupt (zero-length file) but another Page 6 disk has it. The TOS 1.4 update was on the Suzy B software CD 2, available from the Internet Archive. STOS 3D 1.11 is on FaST Club programming disk 466 from TOSEC IIRC. The possible version 1.02 STOS Maestro compiler extension file was in a TGreenwood STOS-related archive, also available from the Internet Archive. There are other sources for some of these, but the TOS 1.4 update took some finding.

Incidentally all versions work in STEEM providing you have a compatible TOS version. I've been meaning to tell Atari Mania that their sick faces for their STOS 1.03 download - http://www.atarimania.com/utility-atari ... 23327.html - are unnecessary. It works fine provided you're using UK TOS 1.2 (I haven't checked with TOS 1.00, but that should work too).

STOS Paint and STOS Word were both mentioned in adverts as incentives to join the STOS club. STOS Paint 2 is available from Page 6 again. I'm sure I found STOS Word somewhere too, I just can't remember where ATM.

I've still got some sorting and deduplicating to do for accessories and extensions, but I think I have some more recent versions and registered versions for stuff that's on the STOS Time Tunnel - almost all from downloads (maybe one or two from some ebay stuff), but not necessarily easy to find.

Though I have not updated that page in a long time. I don't think there is a scan of the STOS manual itself. Saying that, I'm sure I scanned it ages ago but can't remember now. I've not updated the STOS site for a long time, but if you have anything missing then you can send them to me and I will add it to the page in due time

There's a scan of the STOS main manual out there somewhere, the discovery pack version is very nearly identical, but I can send all my scans anyway. Do you have a size limit for attachments? The discovery pack STOS manual is 155MB on its own (though the original STOS manual is "only" 75MB for what should be the same quality - odd), so I may need to split these up and you might want me to reduce the resolution a bit.

You could send them to the atarimania ftp or put them on the atarimania forum or pm me and i will put them on atarimania site

I've found a copy of the STOS manual in PDF form. So no need for that. You are right though. STOS isn't much used by anyone anymore. I started a new site, but it ended up in me going though STOS source code and fixing bugs and updating things. So it just turned into a lot of work where the time would be better spent elsewhere. Though its always good to keep a archive of all this stuff as it is still stuff worth preserving. Its why I did the box scans on some other manual scans a few years ago. Though not much got updated on the site in recent years, though I am getting though stuff slowly

In the STE turbo Pack there is a version of S.T.O.S, I have no idea whether this version is any different from any other STE version but you never know?

I had the Turbo Pack, and yes there are differences. There's only a single STOS disk. This meant that some of the STOS files had to be removed. Bullet Train was not included. Some of the sprite files were not included. And I think a couple of the accessories were not included.
